Description

General description

Fluorescein-5-thiosemicarbazide, also known as FTC, is a fluorescent probe. The FTSC fluorescent spectra is like FITC, a preferred fluorescent tag for proteomics. The fluorescence spectral properties of FTSC-labeled vesicles obtained by reductive amination are fully compatible with the argon laser of fluorescent instruments.

Application

Fluorescein-5-thiosemicarbazide can be used as a fluorescent labeling reagent to label:

• Cell-surface functional groups (glycophorins) in the study of the effect of deoxygenation in the red blood cell membrane.
• Saccharides applicable in polysaccharide imaging in live cells.
• Chondroitin sulfate nanogels applicable in cell-specific drug delivery applications.

Features and Benefits

Fluorescein-5-thiosemicarbazide has the following benefits -

• It displays strong fluorescence property.
• Shows an intrinsic reactivity of the thiosemicarbazide group towards the aldehyde group.
